This paper develops a numerically effective approach to control synthesis for repetitive transverse loads in cantilever beam using an iterative learning control. In particular, the optimal tracking problem for the transverse displacements in the beam are considered. The system dynamics are modelled by a partial differential equation with a biharmonic operator with suitable boundary conditions at the clamped and free ends of the beam. The key novelty is the regulation of the temporal dynamics of the system state by a D-type iterative learning control law based on the second derivative of the beam displacement measured at a priori chosen reference spatial locations. The main systems theory contributions of this paper are the analysis of the convergence properties of control law and the development of a numerical scheme for implementation based on a finite element method. A physically relevant numerical example is given to illustrate the application of the new design in the form of dynamic displacement control for a vibrating cantilever beam. |
